Image Gradients - OpenCV
OpenCV provides three types of gradient filters or High-pass filters, Sobel, Scharr and Laplacian. We will see each one of them. 1. Sobel and Scharr Derivatives. Sobel operators is a joint Gaussian smoothing plus differentiation operation, so it is more resistant to noise.

Laplace Operator - OpenCV
Use the OpenCV function Laplacian () to implement a discrete analog of the Laplacian operator. In the previous tutorial we learned how to use the Sobel Operator. It was based on the fact that in the edge area, the pixel intensity shows a "jump" or a high variation of intensity.

Sobel Derivatives - OpenCV
Calculates the first, second, third, or mixed image derivatives using an extended Sobel operator. We calculate the "derivatives" in x and y directions. For this, we use the function Sobel () as shown below: The function takes the following arguments: src_gray: In our example, the input image. Here it is CV_8U.
